It’s also one of the world’s more significant contributors to climate change and, of the so-called ‘developed’ nations, one of the most reticent to abandon its attachment to the fossil-fuel sector. In Australia, carbon drawdown has additional benefits. Agriculture is at once part of the problem and a key to the solution. Farming requires clearing […]
So, a company can purchase a carbon credit that offsets a tonne of their CO2 emissions, because those emissions have been reduced elsewhere. “The first one is based on avoided emissions,” explains Peter Christoff, a senior research fellow with Melbourne Climate Futures at Melbourne University. For example, speaking with the ABC, Macintosh expressed concerns that most of […]
Materials made from carbon fibre are valuable because they are exceptionally strong while remaining lightweight. Now, researchers have come up with a way to make carbon fibre out of an ultra-cheap source: pitch. The carbon fibre produced from this method has advantages other than lower cost of manufacture over traditional carbon fibre, which are typically […]
We’re not using our lands optimally: that is the message of a new study that shows where the world’s major food crops should be grown to maximise yield and minimise climate impacts. The redesign would eliminate the need for irrigation by locating crops in places where rainfall provides the full complement of water needed to […]
The ad is of course, at least in part, a canny business move for a man who’s investing heavily in a particular hydrogen-based future. But to actually make hydrogen fuel requires industrial processes, and it also needs to be stored at -253°C, no small feat. Brown hydrogen is produced from coal, through gasification – a […]
Each took anywhere between five and 20 minutes. The answer is, of course, somewhere in between. Most people won’t know exactly how many kilometres they drive or fly in a year, nor will they care to tot up their precise electricity usage by the kilowatt hour. The Australian Greenhouse Calculator was, when it still worked, […]
Suzi Kerr, chief economist at Environmental Defense Fund , says the Climate Action Teams model partners wealthier developed countries with developing countries to reduce emissions globally. It is about increasing ambitions at an affordable cost, and not about using the mechanism to replace or avoid domestic targets and objectives for net zero. “We would want […]
In July, the carbon capture and storage facility at the Gorgon gas plant undershot the target it had been set by the West Australian government. Gorgon’s initial Environment Protection Authority approval depended on storing 80% of the CO2 it produced, leaving a significant amount of CO2 to make up. There’s never been a more important time to […]
When Sylvia Little fried her eggs at her Adelaide home one November morning in 1969, she became Santos’s first customer for natural gas from Moomba, 800 kilometres north in the Strzelecki Desert. It is doubtful Mrs Little would have known or cared that the natural gas originally contained CO2 when it emerged from the ground […]
